This invention relatestopouring stoppers for ink bottles and the like,and has for one of its important objects to provide a simply constructeddevice of this kindwhereby leakage of the ink or other liquid from thebottle 3 or container when the device is not inuse will be effectuallyprevented.

.It isanotherrob'ect of the invention to provide a pouring stopper ofthe type in which a removableclosure cap is provided for the liquiddispensing passage and the 1 air vent passage, and in which saidpassages are so arranged ordisposed With respect to l the structure ofthe stopper. that back pressure through the vent passage and the raisingof the liquidlevel in thedispensing chan I p 7 body sectlon 8, this s desurface of the tapernel or passagewhen the closure cap is applied willbe prevented. p q a It is a furthergeneralobject of the invention toprovide a pourout stopper of the above kind whichis of suchform andconstruction withrelation to the outlet end ofthe liquid passage thatthe flow of the liquid therefrom posed in upright positionandaccumulation of the'liquid on the-external surfaces of the stopperavoided. 3 1

With the above and other objects in view, the invention consists in theimproved pourout stopper for ink bottles and the like, and in the form,construction and relative arrangement of its several parts as will behereinafter more fully described, illustrated in the accompanyingdrawing, and subsequently incorporated in the subj oined claims. In thedrawing, wherein I have disclosed one simple and practical embodiment ofmy present improvements, and: in which similar reference charactersdesignate corresponding parts throughout theseveralviews V Figure 1 is avertical sectional .view showin one preferred embodiment of thepresent binvention; 3 3 Fig. 2 is a side elevation of the device, the closure capbeing applied thereto, and

3 is a similar view with the closure cap removed. 1 I 1 Referring indetail to the drawing, 5 designates the bottle or containerjwhich may beofany desired form, shape and capacity, and

will be cleanly cut off when the bottle is disisprovidedwiththe usualcontracted neck 6. My improved stopper, herein generally indicated at7is preferably formed from hard rubber or other suitable material. Thisstop- 3 .per includes a bodysection 8 of cylindrical form having anexternal thread 9 thereon. One end of this stopper projecting beyondthis threaded body section is of general conical or tapering form asindicated at 10 and laterally deflected in one direction from the :99axis of the stopper to provide anobliquely inclined end ,face 11 of;{reduced area in eccentric relation tothe body section 8 of the stopper.The edge of this end face. at one side of the part 1Q is insubstantiallongitudinal alignment with the thread 9 0n the ing'part 10being concaved as indicated at 12,

while the opposite side surface of said part is convex as at 13.

At the 0th :10 r or inner end of the threaded body 8 of the stopper anannular flange 14 is formed thereonto seatagainst the end face of thebottleneck 6, and;the3diametrically reduced section 15 of thestopperprojects in 15 the opposite direction fromsaidflange with respect to thethreaded section 8 thereof. A bushing or sleeve of cork or other similarmaterial indicated at 16 is tightly fitted on the reduced end section 15of the stopper and 50 hasclose frictional engagement with the innersurface of the wallof the bottle neck 6 so as .to provide an air andfluid tight closure for said bottle neck. 1

The stopper 7 is provided with the longi- 3 5 tudinally extending boreor passage 17 through which the ink or other liquid is decanted ordispensed from the bottle. A part of this passage extends in parallelrelation to the axis of the stopper, the outer end .90

portion 18 thereof being curved and opening upon the obliquelyinclinedend face 11 of the (stopper substantially'in concentric relationthereto. 3 3

The stopper is further provided in suitg ably spaced relation to thepassage 17, with anfair vent passage 19 openingat one ofits ends throughthe part 15 of the stopper and having its other end laterally curvedandopening inthe' region of the thread 9 5g rubber is provided at itsopen end with an internal thread 23 for engagement with thecomplementary external thread 9 on the stopper. At its closed end, thewall of this cap is formed with a shallow conical internal surface 24,the angle of this surface with respect to the longitudinal axis of thecap, being substantially the same as the angle of the obliquely inclinedend surface 11 of the stop-' per 7.

In the use of the device as above described, it will be understood thatwith the closure cap removed, in dispensing or decanting the liquid fromthe bottle, upon tilting the bottle from its upright position, theliquid flows outwardly through the passage 17. This cutward How of theliquid will be continuous and uninterrupted, since as soon as the bottleis tilted, the liquid moves away from one side wall thereof sufiicientlyfor air to freely enter the bottle through the passage and the tube 21.Due to the curvature of the end portion 18 of passage 17 and the obliqueangle of the face 11 of the stopper, upon return of the bottle to itsupright position, the flow of the liquid from said passage will beinstantly and cleanly cut off so that the draining of surplus liquidupon.

the side faces of the part 10 of the stopper is efiectually prevented.

v The cap 22 is now placed over the part 10 of the stopper and engagedwith the thread 9. As the ca is turned and threaded downwardly on tiebody of the stopper, the inlet of the vent passage 20 is first closed.Thus air from the interior of the cap cannot enter through this passageandraise the level of the liquid so that it tends to expel the liquidthrough the passage 17, in the event that the bottle is nearly filled tocapacity. Upon further downward threading movement of the cap, thetapering or inclined surface 24 thereof is finally brought into closefrictional contact with the end face 11 of the stopper, thus providingan absolute seal which prevents any escape of liquid from the passage 17into the cap 22 and upon the external surfaces of the stopper, in theevent that the bottle is tilted from itsupright position. The airtrapped within the cap when the latter is applied,

after closing of the vent passage 19-, is forced inward-1 into thedispensing passage 17 and thus provides an air cushion against thedownward flow of the liquid through said passage when the bottle isinverted. Therefore pressure of the liquid against the surface 24 of thecap is reduced to a minimum and leakage of liquid past the end face 11of the stopper into the interior of the cap is effectually prevented.

From the foregoing description considered in connection with theaccompanying drawing, the construction, manner of use and severaladvantages of my present invention will be clearly and fully understood.It will be seen thatI have provided a pourout stopper for ink bottlesand like containers, which while exceedingly simple in its construction,will also be efficient and serviceable for the purpose in view andeffectually overcomes serious objections which apply to articles of thiskind as now generally known and used in this art.

I have disclosed herein an embodiment of the device, which I believe tobe best adapted to fully attain the purposes of my invention. It ishowever, more or less evident that both the stopper and the closure capmight be made in numerous other sizes and other means than that heredisclosed provided for attaching or applying the device to the bottleneck. Likewise, as to the form, shape and arrangement of the severaldetail features as above described, the device is susceptible of more orless modification. Accordingly, itis to be understood that I reserve theprivilege of incorporating the essential features of my presentinvention in such alternative structural forms as may be fairly embodiedwithin the spirit and scope of the appended claims.

I claim l.-A pourout for bottles having a liquid closure member andmeans for adjustably connecting said member with the pourout, saidmember having parts operating successively in the adjustment of saidmember in one direction to first close the inlet end of said ventpassage and thereafter seal the outlet end of said dispensing passage.

2. A pourout for bottles having a liquid dispensing passage the outletend of which opens upon the end face of the pourout and an air'ventpassage the ingress end of which opens upon one longitudinal side of thepourout, and a closure cap rem'ovably and adjustably threaded upon saidpourout and havingiparts successively operating in the adjustment ofsaid cap in one direction to first close the inlet end of said ventpassage and thereafter seal the outlet end of said dispensing passage.

3. A pourout for bottles comprising a body having a tapered end portionextending in divergent relation to the axis of said body and terminatingin an end face of reduced area obliquely inclined relative to such axis,said ber havin body having a liquid dispensing passage extending throughsaid tapered end portion and having its outlet end opening upon saidinclined end face thereof, said body member being further provided witha vent passage having its ingress end remotely spaced from the outletend of said dispensing passage opening upon the circumferential face ofsaid member, and a closure cap having an ad justable threaded connectionwith said body member, the wall of said cap in its adjustment to appliedposition, first closing the ingress end of the vent passage, and saidcap having an internal end surface frictionally engaging said inclinedend face of the body member in the further adjustment of the cap to itsfinal position to seal the outlet end of the dispensing passage.

4:. A pourout for bottles comprising a body member having an externalthread and liquid dispensing and air Vent passages extending throughsaid body member, said air vent passage having its ingress end laterallycurved and opening on theside of said member in the region of thethread, and the liquid dispensing passage extending longitudinallybeyond said ingress end of the vent passage and opening upon an end faceof said body member, and a closure cap internally threaded foradjustable enga ement with the threads of the body mem er and operatingupon adjustment thereon to its applied position to first close theingress end of the vent passage and thereafter by engagement of aninternal end face of said cap with the end face of the body member, toseal the outlet end of the dispensing passage.

5. A pourout for bottles comprising a mema tapered end portion divergingfrom the dongitudinal axis of said member and terminating in an end faceof reduced area obliquely inclined relative to said axis, said memberhaving a liquid dispensing passage having its outlet end opening uponsaid end face of the body member in concentric relation thereto, theexternal surface of said tapered end section of the body member at thelower side of the outlet end of said passage being longitudinallyconcave.

In testimony that I claim the foregoing as my invention, I have signedmy name hereto.
